Michele: The job involved tracking the stunt double’s heads with the singer’s heads. I noticed tracking dots on the stunt double’s cheeks, nose and chin in your photos. Jemaine and Bret were shot against a greenscreen and with a green cape. How did you get it to match? Can you talk a bit about the process of tracking and rotoscoping and matching angles?

Dave: This was a very tedious process that had to planned out for the entire video factoring in the limitations we were facing. We had placed tape on the doubles faces for reference as to how their heads rotated and twisted. We made sure to keep our doubles aware of what was happening in each shot, but allowing them room to perform their stunts.

Dave: Some of the takes were really wild and crazy and we would have to come in and tone down the movement a little to make sure we were going to able to recreate the same move on the greenscreen with Bret and Jemaine. The most difficult part was getting Bret and Jemaine to match these moves and be able to maintain lip-sync. On set (greenscreen) we would run each guy through individually and have them watch a monitor playing back the footage from the shoot. This footage was played back, mirrored in some cases, and slowed down to 50%. This gave the guys a chance to lip sync and get the head movements down.

This is really amazing… I could just imagine the great deal of rotoscoping and motion tracking work that's invested into this project… I must say bravo to the team behind this project. You really couldn't tell the difference.. Hehe.. Really great work.
